My picture looks like this. It shows some percent variation but, due to fluctuations, curves are not very smooth at all.
I would like to draw a smoother image, without altering too much the data (it is okay if the graph is not a perfect representation of the data). I am using matplotlib to draw the data, and my code looks like this:
x = df["Value"].shift(period)+1 y = 100*df["Value"].diff(period)/(period*x)
Basically, it draws the variation from the total over a period. What is the suggested way to alter the points (possibly drawing them alongside) the original data, so that the graphs do not look so jagged?
I tried just drawing every other third point, doing:
w = x[2::3] z = y[2::3]
but I am sure there are better ways to do this. Again, this is for a nice representation only and I am mostly interested in showing a trend or any variation of it, not in showing the exact data points.
