RenderPlotItemDigital

Data plotted as digital data recording.

@ozlb , since you seem to be interested in the plotting project, I wanted to make you aware that I am in the process of changing the API to address several issues and feedback from the ImGui community, primarily: 1) the removal of C++ STL containers, 2) the removal of state managed by the user (i.e. no more PlotInterface or PlotItems are needed), 3) a more ImGui-like API (i.e. BeginPlot()/EndPlot())

The new API is nearly complete, and is being hosted here (rebranded as ImPlot):

I have modified mahi-gui master to now include ImPlot in the 3rdparty directory. The main ImPlot demo has been added as an example to mahi-gui. I also removed the original imgui_plot.hpp/cpp files and examples.

Today or tomorrow, I plan to make a post at the ImGui repository about the new library and features.

Thanks. Actually i need some time in order to get familiar with new API, it's totally different...
As already mentioned, my wondering features are:

• digital channels (as recently introduced but now gone...)
• multiple y axis and drag/drop channels over y axis
• cursors to analyze and display data: delta time, peak min max values, average
• save as "screenshot"
• import/export data and settings
  Are you interested on?

PS: about huge data handling, maybe I'm ignoring something, but have you ever cosidered to handle in different way the "sub pixeling"? I mean, during points for loop cycle, util x "pixel" point will remain the same (due to x wide zoom), instead to plot multiple overlapping lines, while x coorinate is the same consider the y most deviating point. In this way you reduce the total amount of lines and you don't loose spikes of y in wide zoom mode.

Let's move this discussion. I've answered your questions here:
