However, when I plot the graph only a fraction of the datapoints are displayed but when this graph is exported to png, tif etc all data points appear and the plot is as it should be. Why is this? How can I display all the data points in Origin?
Thank you.
I searched here for an answer but didn't find one.
You have an old version of Origin? In later versions, a "Speed Mode" watermark will show on the graph, and you can turn it off from the Layer tab of Plot Detals dialog.
