Cursors like on an Oscilloscope?

[davisoa]

We use KST extensively to analyze log data in a very similar way to how Oscilloscopes are used. Because of this, we would love to have movable cursors that display the delta, min and max (for both X and Y) displayed between 2 arbitrary points on a plot. The arbitrary points would need to be movable via dragging or something similar. Right now we are copying values to excel or something similar and performing the calculations manually.

Maybe an easier feature would be to have this summary information displayable for the entire zoom level (one wouldn't have to implement a line in the plot that could be moved around).

Would it be useful to others to have this feature (or something similar)? What do you think about this idea?

Thanks in advance for any feedback.

Hi. Thanks for the feature request. Sorry I hadn't noticed this 'til now. We normally do everything through the kde bug list.

Currently, this is partially implemented using 'markers'.

Move your cursor to the first point, and hit 'C'. This will drop a marker there. If you have "highlight data points" selected from the toolbar, then the point will be at the nearest data point. Otherwise it will be wherever the cursor is.

When you move the cursor, the statusbar will report the difference between the two points.

But it does not report statistics - though others have requested this feature. If you request it in the kde buglist, I will have a greater chance of not forgetting about it :-)
