Fastest Way to Load data for Surface

miked · Post by **miked** » Sun Aug 22, 2004 9:41 pm

Is it faster to load and present data by using the AddXYZ or AddArrayXYZ?

I am currently using AddXYZ and it takes a while to render. If it's Faster to use AddArrayXYZ, do the x&z-array's need just enough data for each point along the x&z's-axis of the chart or does it need an element for each Y data point?

scenario 1
xArr.size = 12
yArr.size = 144
z.size = 12

or

scenario 2
xArr.size = 144
yArr.size = 144
z.size = 144

Thanks!

There's a good article written by a colleague of mine on speed techniques here:

although written for TeeChart VCL it is also very relevant to TeeChart AX.
