thirdcoast-grapher's Introduction

grapher

This is the 3rd coast telemetry client.

Description

Team 2767, Strykeforce developed this application to obtain telemetry information from a robot. This can be used to optimize control systems for the motor controllers or vision systems. Coded by Greg Rabick and Sam Rabick

Development

This program was developed in LabView 2016.

Other add-ons that are required to open the labview code include the following (these can be found by downloading and installing the national instruments VI Package Manager):

JKI JSON (ver 1.1.10.37)
JKI REST client (1.2.1.12)

From LabView, open the project file, SamsGrapher.lvproj Within the project, the main .vi is: SamsGrapher.vi

Deployment

Executable

The project can be compiled into an executable if you have the national instruments Application Builder add-on installed. This is a standard add-on that comes with the installation of National instruments Labview if/when you install the development version of Labview that is provided to FIRST teams.

From the project window, right click "build specifications".
Select new->Application.
fill in the window that appears. the window is pretty smart about guessing the correct settings to use, so Default settings should work without modification.
make sure SamsGrapher.vi is selected as the source.

installer

The project window also allows you to create an installer that will install both the grapher application as well as the labview run-time engine (required for computers that do not have the labview development environment installed).

build the executable as defined above first.
From the project window, right click "build specifications".
select new->installer
fill in the window that appears. the window is pretty smart about guessing the correct settings to use, so Default settings should work without modification.
make sure the SamsGrapher.exe is selected as the source file, and ""

thirdcoast-grapher's Issues

Selection Windows when the Grapher fires up

Currently there appear to be artifacts in the Talons and selected data windows that is always the same. This should be cleared and then populated with the current data from TCT. If no TCT is found, we should leave them blank and tell the user that no TCT was found.

add instructions-for-use in the labview front panel window(s)

we should add instructions for key functions such as selection of parameters (double click).

Autoscaling

Disable all autoscaling. Both the x and y axis.

If we wanted to leave a single capability that allowed the user to draw a box on the graph and then have to graph expand to the box, that would be useful AS LONG AS it does not change the true axis limit AND there is a reset button to take you back to the full axis scaling you had before you did the zoom window.

Digital readout on the Grapher page

Any unused channel should just be grayed out and not show any numbers.

We may also want to change the digital readout font to white vs black. Might be more contrast against the axis colors.

Allow manual entering of time range

Allow the user to enter a number in the time range box to set the exact time range.

Folder the configurations are saved in

It appears the default folder that comes up is write protected. You must change the folder for this feature to work. I would recommend doing something out that as most users will not know they need to do this and just presume the save does not work.

Graph line and dot colors

When you select a color for a graph line or dot, that color shows up in the user selected color list. But that list is not saved when you exit the grapher. We need to save those colors so that you don't have to recreate them each time. Alex did this in the old grapher and it was a big help

Remove scrolling for scale adjustment

Save configuration does not same the X axis scaling

Just need to add the X axis scaling to the saved config files.

Grapher needs a 5th Y axis

There are times where you need 5 different scales to get everything on the screen

X axis readout

The plus and minus buttons on the X axis are PERFECT! What would be a nice add is a digital readout that tells you how many seconds are displayed on the entire X axis. When I zoom in and out I normally know where I want to get to but have to spend time looking at the scrolling numbers to figure it out. A display would eliminate that challenge.

Exit Application button doesn't exit the application

Might as well remove it since everyone probably just X's out of the app anyway.

Port selectioon when the grapher fires up

We should only allow the user to change the Team number. The rest of the info should be hard coded. TCT has the ports hardcoded so there is no need to change them in the grapher. At most we would want to build the standard IP address (10.27.67.2) from the team number and then perhaps let then use a different IP address incase they have something strange in the Roborio. But the cleanest answer might be to just ask for the team number and force everyone to follow the standard protocol

Grapher Y axis

When you use the Y axis configuration button to change the Y axis legend, the legends from all axis print out on top of each other. Say for example you want to change the number of decimal places.

If you just changes the end points on the legend itself, everything works fine.

Fix spacing on parameter names

Simple fix, not worth new release.
