Insert old data points
Right now I have drop old data turned off for my graph with several SampleDataSeries on it. However, after about 6 hours the application eats up all of the RAM and stops. I know I need to turn DropOldData on, but what do I do if the user wants to review data that has been dropped? There isn't an ins...

Re: DeleteOldSeriesData define what old data is
I ended up implementing this by hard-coding that the data before the x axis minimum - 30 should be removed. It would be nice if it were a property that could be easily changed, but it works for now.
Here's what I did.
double dDropBeforeX = m_dMinimum - 30; // seconds

DeleteOldSeriesData define what old data is
Hello, Currently old data is defined as anything before the current window that is being rendered. It would be nice if I could define when data is considered old. I'd love to be able to specify a time like 60 seconds for the old data threshold so any data older than 60 seconds would be removed. Than...

Segment render overlapping
Is there any way to keep one segment's graph data from overlapping into another graph segment?
I have a series of segments that I do want to overlap and a single segment that I don't want anything to be drawn in except those lines that are in the segment.
Thanks,
Matt

Hello,
The y-axis title's width is set by it's text. Is there any way I can set the width of the title manually? I'd like all of the titles to be the same width.
Thanks,

Re: LineColletion doesn't render when y axis is adjusted
I found out what was going on. There's a bit of code that skips rendering the line collection if its series stats are invalid. I simply commented this code out and it all worked.

I was incorrect about the behavior. It actually does the following. 1. I add a ChartEventMarker at a point in time, 8 seconds for example 2. The graph data is behind the ChartEventMarker in z-order 3. The sweep wraps around and passes over the ChartEventMarker, this paints the graph data over the ma...

Re: Converting axis values to screen coordinates
I was doing this, but getting odd results. Then I realized that I needed to wait for the graph to load before the ValueToCoord methods would work.
There's a Loaded event on the chart that you can hook into.
Hopefully this saves someone a little time.
