How to speed up manipulations of plot with a lot of data
2 views (last 30 days)
I have time series with 20000000 samples that I am plotting in R2016b for data exploration. I would prefer not to downsample or subset the data because I have to look at closeups scattered through the whole time series, and I need to be able to zoom in/out, select lines to extract values, etc. Possibly due to the data volume, the Figure Interactive tools (selection arrow, pan icon, data brush ) are periodically grayed out on the figure toolbar. Sometimes the cursor disappears inside the figure window if I want to zoom in. These down times can be several minutes.
Are there any tricks for manual manipulation of high-volume plots, such as avoiding use of markers?
