Does Microcharts have mobile touch support to view data? e.g.( touch a actual point and the data is displayed over it)

Please add FontSize for labels.
How does look charts now in FullHD displays:

Project Type: Native Android & iOS (not forms)

I'm trying to add Microcharts to a "Class Library (Legacy Portable)" project, but the latest version (0.7.0) won't install because it's not compatible. However, 0.5.2 installs fine. .Net Standard is the future, so I'd like to ditch Legacy Portable, but my project is structured around ReactiveUI and the latest stable version (7.4.0) is not .Net Standard compatible.

EDIT: (9/19/2017)

I found this ReactiveUI link that solves my problem: https://reactiveui.net/docs/getting-started/netstandard
Regardless, it may worthwhile to add support for Portable Legacy, since libs are still in the process of migrating to .Net Standard.

Thank you for this simple, yet quality package!

If you put into appveyor this is easy to do like I do here: https://github.com/jamesmontemagno/FloatingActionButton-for-Xamarin.Android/blob/master/FloatingActionButtonForms.nuspec

else you would have to just match up the number manually.

As you can see that two labels are overlapping when values are small relatively and close to each other.Can anybody guide me how to resolve this.

Do work it with PCL Xamarin Forms Solution?

In the new pre-releases forms package including 0.80pre to 0.83pre, doing a simple chart based on the GitHub example like
chartView.Chart=new BarChart() { Entries = entries };
would throw the set_chart method not defined error. the same code works well in 0.62. can't test it in 0.70/0.71 due to .net compatibility errors.

Hi, I followed the steps on Quickstart section and I get this error when I try to run the application:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation

any suggestions???

It would be cool if there's an option to add animation on appearing. :)

Hi @aloisdeniel,
First of all, congratulations for the library. Great work!

I started trying it to be able to talk about it during the next event in my community.
I created Xamarin.Forms projects but I did not find the binding for Entry object (next ChartEntries).
I thought about creating a new custom object for every chart available.
This is an example of a code, what do you think?

public class MicroDonutChart : Microcharts.Forms.ChartView
{
    public MicroDonutChart()
    {
         Chart = new DonutChart();
    }
    public IEnumerable<Microcharts.Entry> ChartEntries
    {
         get { return (IEnumerable<Microcharts.Entry>)GetValue(ChartEntriesProperty); }
         set { SetValue(ChartEntriesProperty, value); }
    }

    public static readonly BindableProperty ChartEntriesProperty = 
        BindableProperty.Create("ChartEntries", 
             typeof(IEnumerable<Microcharts.Entry>), 
             typeof(IEnumerable<Microcharts.Entry>), 
             null,
             propertyChanged: HandleChartEntriesChanged);

    static void HandleChartEntriesChanged(BindableObject bindable, object oldValue, object newValue)
    {
        ((MicroDonutChart)bindable).Chart.Entries = (IEnumerable<Microcharts.Entry>)newValue;
    }
}

XAML part:

<local:MicroDonutChart ChartEntries="{Binding Path=ChartEntries}" HeightRequest="180"/>

Hi,

I followed few sites and trying to achieve Charts with help of Xamarin Forms in TIZEN but no luck,
Could you please let me know.

My Code 👍

Will be renderers with bindable properties for XF?

Hey there, I'm currently localizing an application and I've noticed that there isn't any way for a user to pass in a typeface for chart labels. Making it impossible to localize for languages like Chinese.

Request:
Please expose Typeface properties for your chart controls to apply typefaces to labels.

The project need information about code conventions/contributing guide.

I can help if you tell me what is the plan.

Would it be possible to have a null value, the reason is I want to show every hour of the day (or day of week etc) but I might not have a value for that hour. I still want to see the label but the chart would just bypass showing a bar, dot etc

Any plans to support a chart title, x-axis label, and y-axis label? I do not see a way to add these.

Seriously?

Labels are cut off - any way you can add rotating / wrapping labels for the data points?

This Microcharts looks very good, but I want to add some gestures on it, such as tap、pinch、pan, which can change source and charts dynamiclly.
Thank you for replying!

Hello there, I'm using Microchart for Xamarin.Forms. Great tool so far! However, I found an interesting bug:

According to the tutorial, the max value will become the value of the chart with the highest value. In my case, the max value of the chart is that divided by 2. If I increase the 'MaxValue' property to 400, it still does not give me the desired max value.

Is this a known bug? Am I doing something wrong in my code? Please let me know. I'm using 0.8.1-pre.

Can i rotate entry value and label to show horizontal

Hello,
I need to handle null values on linechart... I don't want to draw a point on 0... i want make a invisible point with the average of the last valid point and the next valid point... is it possible?

When use Arabic characters as titles, a square appears in place of the title

We chose MicroCharts.Forms 0.6.2 because there is an issue of dependencies on 0.7.0
Xamarin.Forms 2.3.4.267

Implementing a donutChart in my android application and I'm getting an invalid Cast exception error all of a sudden after it worked fine before. What could be the issue?
Screen shot attached.

Error is occurring on:
chart = new DonutChart(){Entries = chartSeries };

chart series is Entry array:
chartSeries = new Microcharts.Entry[] { new Microcharts.Entry (A) { Label = "100-75", ValueLabel = MakeAPercentage(A, total), Color = SKColor.Parse("#00D83E") }, new Microcharts.Entry(B) { Label = "75-50", ValueLabel = MakeAPercentage(B, total), Color = SKColor.Parse("#64BCFF") }, new Microcharts.Entry(C) { Label = "50-25", ValueLabel = MakeAPercentage(C,total), Color = SKColor.Parse("#FFD64A") }, new Microcharts.Entry(D) { Label = "25-0", ValueLabel = MakeAPercentage(D,total), Color = SKColor.Parse("#D30D1B") }

Hi,
pre-0.8.3 installed
The Code which works for USB connected deployment is not working in Xamarin Live player.
It gives System.IndexOutOfRangeException in Entries property.

Hello!

There is a way to specify the location to show the label?
For example, if I use a RadialGauge and my label value or text is big, it goes over the chart graphic.
So, is there a way to choose if I want the label in the top, bottom, left, right of the graphic? Or something similar to that that can help me?

Microcharts is absolutely gorgeous and wonderful, however when I attempt to put it on a page along with any other View-based element (Label, ScrollView, Grid, etc.), the chart becomes invisible.

For example:
<forms:ChartView x:Name="ServicesChart" HeightRequest="50" />
will show perfectly fine, however if my file has this:
<forms:ChartView x:Name="ServicesChart" HeightRequest="50" /> <Label>Test</Label>
the chart is nonexistent (without height or width) and I see the label displayed at the top of the page.

Likewise when I add a ScrollView, Grid, or other View-based element to the page.

Since there's no (easy to find) information detailing the differences between the nuget packages Microchart and Microchart.Forms, I think it'd be very useful to rename Microchart.Forms to Microchart.XamarinForms.

I seem to be getting this error in my project even though I have both Microcharts and Microcharts.Forms included in my project. I'm using version 0.8.0-pre for both. Sorry if this isn't an actual issue.
EDIT: Fixed it by upgrading to 0.8.2-pre.

Is it possible to use Microcharts also when data has to be dynamically added to a chart, instead of statistics-like static data ? For instance if new data comes asynchronously from a WebService, more or less cyclically. Are there any samples for this scenario available ?

Can anyone point me in the right direction.

What api are you using in Xamarin.Forms that requires for you to target the latest version?

Hello, i'm using your Nugget to create some nice looking charts, but the Donut Chart in Portrait mode is a little too big for the screen and it also overlaps the text.

I could use landscape (and I do) but I'm... "Asked" for it to work on Both orientations. Is there a way to make the donut chart smaller?

Hello,

I installed Microcharts.Forms to my project and tried to add in a content page "<microcharts:ChartView x:Name="chartView" />" as in the example, but when I run on iOS I get the following error: "Failed to resolve assembly:'Microcharts.Forms, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null".

Version 0.7.1 for Microcharts.Forms and I am using Xamarin Live Player.

Thanks

Hey there!

Thanks for this great library. I was trying to change the LineSize attribute of the RadialGaugeChart type and i experienced that whenever i set it to a small size, something like 10, i can't resize the whole chart. So if i only got one entry the chart will appear really small and only gets bigger if i increase the line size.
What i want to achieve is a big chart with a thin line. Any ideas?

Best regards

To make a chart ( X: time 9:50 , 9:51, 9:52 , 9:54, 9.58....... ) , ( Y: value , 0,1,2,3,4 .. )
Is it possible ?

Hello,
Is it possible to make in LineChart two or more lines in chart?

Something like this: https://i.stack.imgur.com/axSKb.png

Great tool!

Question: I would like the ability to show multiple datapoint for the same category to provide a simple visual comparison. Any plans to support something like this in the near future?

Something similar to this:

I want to make the Microcharts clickable and get the clicked portion data. Is it possible?

Entry exists in both Xamarin.Forms and Microcharts namespaces, which confuses users.

Hi,

I have created a .Net standard forms project and included 'Microcharts.Forms' from nuget in all projects in solution.
I can't able to get access of 'Entry' and other Chart types (like LineChart, BarChart, PointChart ...). Is it supported for .Net standard projects or did i miss something?

Hi fellows, I am new in Xamarin framework and currently using Xamarin.Forms to create an app with the Target Framework PCL4.5 profile 111. I have installed Microcharts.Forms nuget package and done the setup.
When I debug on iOS platform the chart generated perfectly, but on android platform, it crashes and display the following error.

It is about something unable to find the assembly file. Can I use some help? Thx alot!

P/S: I am using Microcharts.Form v0.6.2, and I am unable to update to latest 0.7.1 due to I got an error saying "Package Microcharts.Forms 0.7.1 is not compatible with portable45-net45+win8+wpa81 (.NETPortable,Version=v4.5,Profile=Profile111).
