Odd behavior when add_heat_series is lacking values.

[laundmo]

Version of Dear PyGui

Version: dearpygui==1.6.1 Operating System: Windows 10

My Issue/Question

When using add_heat_series and supplying fewer values than rows*cols would imply, the following odd behaviors happen:

• The rest of the heatmap is filled by zeros that randomly do or don't have a negative sign.
• Sometimes the app crashes before showing everything.
• Sometimes the one of the values shown is 1.

To Reproduce

Steps to reproduce the behavior:

1. Run the minimal example below
2. close and reopen it multiple times
3. potentially change the number or content of values provided to add_heat_series for further randomness

Expected behavior

Either an error when add_heat_series is lacking the amount of values required, or consistent behavior for missing values.

import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.window() as primary_window:
    with dpg.plot(height=500, width=500):
        dpg.add_plot_axis(dpg.mvXAxis, label="X", no_gridlines=True)
        dpg.add_plot_axis(dpg.mvYAxis, label="Y", tag="yaxis_tag")
        dpg.add_heat_series(
            [2, 3],
            4,
            4,
            parent="yaxis_tag",
        )

dpg.create_viewport(width=600, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
