thanks.

Any plans on adding a Gauge chart?

• I have searched for existing issues

I installed 0.0.24 and am trying to use SmoothLine but nothing is appearing except for this error now:

<Error>: Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.

Any solution? I tried using some sample data but still doesn't work.

[[{x:0,y:1}, {x:1, y:1}], [{x: 4, y:5}, {x:6, y:4}]]

Hi!

I have tried to run the example as described in the readme. I tried it on 2 different computers. On the second one I did a completely fresh install of react-native / android-studio, just to be sure.

Both computers run on Ubuntu 16.10. When i am building with "react-native run-android" I always get the following errors:

Anyone else getting this error?

So I upgraded my project to RN 0.40 and pathjs charts doesn't seem to work anymore as seen below. I read in another issue that this library may not work with 0.40 just yet but wanted to make sure that's the case and that there is no workaround.

I'm using pathjs-chart 0.0.24 and RN 0.40 running on iOS.

Drawing a basic bar chart like this:

...
<Bar data={data} options={options} accessorKey='v' />
...

Cheers.

This would bring more safety and find bugs earlier. Issue #49 was the catalyst for this.

We can start off a page at a time and slowly add more support over time.

(An extension of #17)
There is an extra vertical gridline on the StockLine chart with a specific data set.

It can be reproduced with the following on both emulators for iOS and Android (Nexus 5, Android 7.1.1 - API level 25) using the following:

import React from 'react';
import { AppRegistry, View } from 'react-native';
import {StockLine} from 'react-native-pathjs-charts';

export class StockLineExample extends React.Component {
  render() {
    var data = [[{"x":3,"y":71},{"x":6,"y":75},{"x":7,"y":61}]];

    var options = {
      width: 275 ,
      height: 200,
      color: '#2980B9',
      margin: {
        top: 20,
        left: 20,
        bottom: 20,
        right: 15
      },
      animate: {
        type: 'delayed',
        duration: 200
      },
      axisX: {
        showAxis: false,
        showLines: true,
        showLabels: true,
        showTicks: true,
        zeroAxis: true,
        orient: 'bottom',
        tickValues: [],
        label: {
          fontFamily: 'Arial',
          fontSize: 8,
          fontWeight: true,
          fill: '#34495E'
        }
      },
      axisY: {
        showAxis: false,
        showLines: true,
        showLabels: true,
        showTicks: true,
        zeroAxis: true,
        orient: 'left',
        tickValues: [],
        label: {
          fontFamily: 'Arial',
          fontSize: 8,
          fontWeight: true,
          fill: '#34495E'
        }
      }
    };

    return (
      <View style={{flex:1,alignItems:"center",justifyContent:"center"}}>
        <StockLine
          data={data}
          options={options}
          xKey='x' yKey='y' />
      </View>
    );
  }
}

AppRegistry.registerComponent('example', () => StockLineExample);

debug模式一切正常 编译成release以后 安装完成 打开就直接报 not find DSO libcsslayout.so
release过程中 没有报任何错误
目前RN版本0.41.2

I have installed this library by the guide also used your example as starting point (used your example data also). But when i opened it the chart wasnt showing properly

I have tried this with every chart, its the same there is always "offset" (see picture). Also i tried to change margins (i have set chart margins to 0 and margins of the View to 20) this sets dots ok but since the x,y axis are out of view their titles don't show.

Also to add i am using Android 6.0.1 on device.

  I had  added  the library to My React Native project:

npm install react-native-pathjs-charts --save
react-native link react-native-svn.Then do like example pie ,import { Pie } from 'react-native-paths-charts' and run My project in android ,it output 'Unknow named module::'react-native-paths-charts''.
What should I do to resolute this ?I predicated somebody can help me.

My dataset has the following X values: 1.78, 1.83, 2.0, 2.46.

As you can see, it gets quite ugly...some (simple?) solutions would be to limit the number of digits after the decimal point (I imagine 2 digits for the fractional part would be sufficient for scenarios that involve mobile graphs....), or rounding the fractional part after a number of digits over the decimal point.

Edit: I see this is an issue from the lodash range method...maybe since lodash is MIT licensed the method can simply be copied and improved with the proper handling?

I want to have my y-axis always start from 0 irrespective of the min value of my data. Is there a way to achieve this?

I would like to put up a graph with no data, just x and y axes. If I pass in empty data arrays, I get an exception. How can I draw an empty graph?

When I run the example in [email protected]/[email protected]/[email protected], I meet a error :

undefined is not a function (evaluating '_instructionstypeof Symbol==='function'?Symbol.iterator:'@@iterator'')

points
path.js : 178

render
Radar.js : 99

How to resolve this problem?

Is there a way to set the line thickness/width? If we are to use showAreas: false it becomes really difficult to see the lines.

Hi there,

I've created a new React Native project (RN 0.30.0, React 15.2.1, Node 4.4.0) and installed this package as follows:

$ react-native init PathJSChartsDemo
$ cd PathJSChartsDemo
$ npm install --save react-native-pathjs-charts
$ rnpm link

I then imported Bar and added the example and data the index.ios.js file:

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';
import {Bar} from 'react-native-pathjs-charts';

class PathJSChartsDemo extends Component {
  render() {
    return (
      <View style={styles.container}>
        <Bar
          data={sampleData.bar.data}
          options={sampleData.bar.options}
          accessorKey='v'/>
      </View>
    );
  }
}

const sampleData = {
    bar: {
        data: [
            [{
                "v": 49,......

I noticed that rnpm link completes with no output, in case that's relevant. When running the app I get the error in the issue title. The top of the stack is createNativeComponent.ios.js:36 in react-native-svg/lib. Do you have any ideas what I might be doing wrong?

Thanks!
James

Before filing an issue please ensure the following boxes are checked, if applicable:

Hi I'm using react-native 0.32, and there are no numbers for axis on android, only one in top left corner.

I checked for bar graph... there are also no labels on axis...

Hi

When trying out the examples I'm getting the following error for them all (only tested on android):

"Error while updating property 'd' in shadow node of type RNSVGPath"

This is my set up:

 "dependencies": {
    "react": "15.4.2",
    "react-native": "0.40.0",
    "react-native-svg": "^5.1.4",
    "react-native-pathjs-charts": "0.0.24",
    ...
    }

I've run react-native link react-native-svg and it linked successfully.

Has anyone else has this?

I've found the same error message here: steveliles/react-native-circular-slider-example#1 but I am able to run this example.

Thank you for your help.

I added one of your chart exemple, and i have an empty view. I added a text before to be sure it wasn't render outside of the visible field....

It should be rendered in the StockLine.

Am i doing something wrong?

LineChart hard codes (lines 71-75, 79-80) the accessor function that it passes to the underlying chartType.

The ability for the using code to pass an alternative set of functions would enable more flexibility for the data structure passed in.

Maybe fall back to this default if a function is not passed.

I'm getting an error when trying to start the example app

I just tried to run the example, using the react-native run-android, but I get this error:

Failed to finalize session : -26: Package com.example new target SDK 22 doesn't support runtime permissions but the old target SDK 23 does.

I'm not exactly sure if this is expected behavior or not, but here's an example:

    let data = [[
        {"x": 8, "y": 82},
        {"x": 13, "y": 70},
        {"x": 15, "y": 120},
        {"x": 19, "y": 80}
    ]]

    let regions = [{
        label: '',
        from: 70,
        to: 130,
        fill: '#18c947'
    }]

As you can see, even though the datapoint is right on the edge of the region, the plot goes under it, which is deceiving and gives the impression that the value is outside of the bounds designated by the region.

Pie chart is always drawn with it's center as parent view's top left corner. How to give the center point as Parent View's center?

When there is only data field, it draw only one line instead of circle.
By the wat StockLine and SmoothLine need minimum 3 ponts of data to build it or if there are less then 3 points it crashes.

In order to let my app work on both phone and tablet, I need to apply flex to everything.
Is there any way to set chart width/height to flex?

NPM package installs [email protected]

From react-native-svg:

react-native-svg >= 3.2.0 only supports react-native >= 0.29.0

I'm currenntly using:
"react-native": "0.36.0"

Can you update the npm package? Currently, I'm using npm install with github link as a solution.

You should update react-native-svg to 4.5.0 or higher. They added support for [email protected], which would be great because I can't use your module on iOS.

Having this issue:

Tried to build in xCode and got all those errors :

I wanted to extend y axis line (showing no data but to be drawn in smoothline graph) in the scale ratio. I just cant figure out how would i do it. this.chartType handles this (if i am correct)

Hi, This is very awesome library.
I just want to ask that how can i represent my data to the color filled.
If there are thousands of data I cannot statically assign color to each of them.

For Example :-
In screenshot How can i make user understand that upper color is for a and below is for b

Thanks in advance for your help

This is my bar chart:

But I want to......:

First bar hide yAxis numbers...

Do you have a way to just do a very basic line chart - or use the existing scatter chart, but connect the points with straight lines?

Thanks for your great library!

I am not sure if (how) this "combination" of a line chart with a "horizontal" line is possible:

Is this possible somehow with the library?

Thank you for any insights you can provide.

Is not an issue but it will be awesome to have a onload property while the chart is loading

Hi, I add react-native-pathjs-charts and link this in the my project.
when running, Xcode'error: "unknow class method for selector UIFont:nil withFamily:fontDict[@"fontFamily"] size:fontDict[@"fontSize"] weight:fontDict[@"fontWeight"] style:fontDict[@"fontStyle"] scaleMultiplier:1.0]; " in the "RNSVG/Utils/RCTConvert+RNSVG.m".
I think the react-native-svn'version is too old, so I npm install react-native-svn@latest and again link, I find the code is different about upper description, and I success run app, but I don't see chats, I still failed.
I don't know the reason, who can tell me why is it that?

Can i achieve something like that?

What I need is just to have a single line with circles at each point.

Like the one from http://andreaferretti.github.io/paths-js-react-demo/

There's an issue with the scale return for the Y axis values when using decimal numbers.

When the scale is from 0-0.5, 0.3 on Y axis is rendered as 0.30000000000000004

When the scale is from 0-1, 0.6 is rendered as 0.6000000000000001 on the Y axis.

Hello, I was wondering whether there is any way to make it visually clear on the graph that a certain data point has gone over / under a specified threshold? To expand on this, what I would like would be something like the ability to individually color bars in the bar chart (red for ones that go over / under a threshold that I maintain, green for others within "accepted ranges"), or like a way to draw horizontal lines over the stockline graph, indicating clearly what the threshold range is, so the user can see when those are exceeded, etc.

If there's no established way to achieve this (which I believe might be the case after a quick look over examples and code), is there a hacky way, or maybe something that I could implement if pointed in the right direction?

Thank you

Hi
For first, thank you for cool library!
How i can scroll chart horizontally?

I tried pass data with state and how can I re-render chart if data has changed.

    return (

It appears I broke many of the charts on the example app in Android specifically on d0de1e3 when upgrading paths-js from 0.3.4 to 0.4.5. I see the following error:

undefined is not a function (evaluating 'data.entries()[typeof Symbol==='function'?Symbol.iterator:'@@iterator']()')

on every type of chart other than the line charts (StockLine and SmoothLine)

It's all in the title: to replicate in the SmoothLineChartRegionsExtended example, simply assign a value for Y of a data point such that Y < min (when min is specified). Example, where min = 30, as you can see, my second data point has Y = 10, which pushes the X axis out of view:

data: [[ {"x": 0, "y": 82.5}, {"x": 13, "y": 10}, {"x": 15, "y": 100}, {"x": 17, "y": 150}, {"x": 24, "y": 50} ]]

I want to show the xKey as a string,but it's a number, i tried to modified it,but it doesn't work.
