Re: [tracecompass.incubator-dev] Plotting a Simple XY Chart
Hi  Geneviève,

I have attached the script (Script.txt) and trace (Sample Trace.txt) files and also a screenshot of the XY chart (trace_XY_chart.PNG) that I am getting. As you can see in the screenshot, the Y axis is taking the quark values. How can I make it take the cpu_load values instead? (The third column in the trace file represents the cpu loads.) 

I have also attached the custom parser that I have used (sample_trace_custom_parser.xml).

Thanks,
Basavaraj

Hi Basavaraj,


It's hard to answer your question without seeing what you did, maybe you could share a screenshot or the script? In any case, make sure the content of the state system that you are trying to display is OK.

Which examples have you used? How did you get to know about EASE? Have you seen this tutorial lab about writing EASE analyses: https://github.com/tuxology/tracevizlab/tree/master/labs/204-scripted-analysis-for-custom-instrumentation

Look at task 6, that shows how to view what's inside your state system before building a data provider. The next task creates a time graph data provider, which could as well be an XY data provider.


HTH,

Geneviève

Hello community,

I have a simple trace that has some event types along with their cpu loads (in percentages) and timestamps. I want to plot a simple line graph (timpestamp vs cpu load in %) for each event type. I have followed the example scripts and by using createXYProvider(analysis, map) and openXYChartView(provider) functions I have been able to get a line graph for each event type, with time stamp on the X axis. However, the Y axis displays quark values. I am not getting how to make my Y axis use the cpu load values instead of quark values. Need support in this regard.

P.S.: I am using _javascript_ in EASE framework.

Thanks,
Basavaraj Munnoli
