Problem with Histogram

[gauriachalare123]

I am trying to draw histogram with most of the data having difference (end- start) = 126,
the histogram is not getting plotted. After manipulating data so that difference (end - start) > 1000000 I am able to see something. Does it need stat and end with some minimum difference to plot the histogram or heatmap?

I had the same problem. Setting the min and the max value in the config solved it.
