Requested solution or feature

It would be nice to be able to see a histogram of values of a dataset.
I work with sensor data, where the heatmaps are very useful see values for each pixel. But sometimes im interested in a histogram over all pixels and frames.
What i did so far is to save the array "hist_values" of this
hist_values, bin_edges = np.histogram(data, bins=50)
to an array and display it using "line" option. Which kind of works, but i cannot display bars and the x-axis is wrong.
