waterfall chart to show response? #46

Open sageless opened 5 years ago

I was interested to see how the response data would look in a waterfall type chart. With the color mapping on the 2d chart, it is difficult for me to tell what the values are just by the color. On the waterfall, I can't say it is much better with the 3d perspective, but the change in height stands out more to me. Other problem with 3d waterfall (and viewing from fixed angle) is there will always be obstructed view of some of the data.

In the attachment, the bottom chart averages out close to 1.0, but can't tell the initial overshoot is increasing at higher throttle.
The second chart shows this with increasing light green and yellow at the bottom. Is the waterfall (3rd chart) having the peaks stand out more?

Maybe if it was larger on another page and showing from 2 angles? But if this chart is included it takes graphs longer to draw so should be optional.

I have some example code if it is of any use to include in some way. But I am not a python developer so it would need some tuning.

Second attachment shows chart with X, Y (response time, throttle) swapped.
