Challenging task
Posted: Thu Mar 26, 2009 4:29 pm
Hey,
I got one request to improve my chart, which looked easy at first glance.
Chart is simple - I have one Line series that displays signal in volts, x- time in seconds (from 0 to about 100)
Also I have some state change data, say, from second 1 to 12 it was "Step 1", then from second 12 to 20 "Step 2", etc. Customer requested to have this info displayed as a colored bar on the top of the chart. This bar should stay still during scrolling/zooming, but should perform syncronized scrolling with main chart Bottom Axis. Each step has it's own color.
I have different ideas :
1. Put horizontal self-stacked bar in the main chart, but how do I reposition it and prevent from zooming ?
2. Simulate it with Top axis colored labels.
3. Place a subchart on top of the main one and sync both charts horizontal scrolling.
None of the above looks trivial , but which one (or another one) you think is more promising ?
Regards
