I have searched this forum with keywords contour and percent, it only
give one irrelevent result.
My problems is how to plot contour in percent.
In my figure, I have use kde2d to generate density of an array with
two dimension point.
Using image and contour could plot it.
But the line contour generated represent absolute value of population,
not how much pecent point within this cycle.
So, i there any function which could accomplish it?To generate a cycle
which could tell me how much percent of points lies in this cycle.
Thank you for your attention
One way to approach it would be to
-create a function that returns the density for each x and y
-assign a density score to each case
-determine the quantiles
-draw the pseudo-3d or contour plot with colors or levels at the
desired proportion.
I think I have seen worked examples of this process, so it may be that
searching on "quantile" instead of "percent" would be more successful.
