Hi Phil, 

> Can the arrows be annotated with a small comment?

It is not yet supported, patches are very welcome, I have two corner cases to watch out for:

1- what do we do when there are hundreds of lines going across the chart

2- how do we handle a line that is crossing the chart, is the label always centered or visible?

Thanks for the interest in Trace Compass

Hi Phil,

Thanks for your interest in the scripting modules! Your views look great!

I'll answer inline below.

Hi,

I am currently using EASE Scripting 0.7 to analyze some LTTNG CTF traces and I have some questions regarding the visualization of the trace data.

Is it possible to modify the color of the arrows created by createArrow() or the color of the different states in the state system?

It is not possible to easily change the colors from the script, either for the state or arrows. Recent modifications to the style API for time graph data provider would make it relatively easy to add this support, at least for state. I'm not sure of the style/color status of arrows though.

Can the arrows be annotated with a small comment?

I do not think so. Maybe Patrick who has worked a lot recently in the time graph vie has a better answer?

And finally my last question, when I use the XY Chart, the data is presented using an line graph. Can I change this to something like a point or asterisk?

Yes! See the documentation for the ViewModule [1]. You can open your view using the openHistogramChartView or openScatterChartView with the same data provider as the openXYChartView.

Do not hesitate if you have any more questions on the scripting for Trace Compass!
