I need to make a line graph in php but my problem is that I need to plot many data points on an image of 600px x 400px. Does anyone have any ideas of how to do this? I tried searching around for a solution but haven't found one. The graph would need more than 600 datapoints so I would have to separate each point by less than 1px which I don't think is possible. I have seen graphs online that plot more than 20,000 data points on relatively smaller images. So I know its possible I just don't know how to do it.
