Hello All, I'm trying to figure out the (automated) way to generate heatmaps from simple data tables with annotated rows and columns. In the end, I need these files to be easily viewed in a browser.
The initial data tables are simple; numbers are row-normalized (values are real numbers varying from -1.0 to +1.0), with rows numbered from a zero to a certain integer, and columns are named with (sometimes lengthy) strings. What I came up with so far is building the heatmap using standard facility with a set resolution of the final png file: Which sort of works sometimes: And fails pretty miserably other times: What I really would like to do, is to make a heatmap with set number of pixels per square, with a set font size (in pixels as well), and then save it as a .png with variable resolution (appropriate for each concrete heatmap). That way, a cell would be always say 10 by 10 pixels, and the text on the right is always 8 pixels tall. Alternatively, of course, it would be very neat to save it in some vector format easily interpreted by the browser, but I have an impression it is not an easy feat to accomplish. Thank you very much in advance.
