Is free openheatmap.com better than Excel? For me it was by far. I used Excel to clean up my data but then it’s heat map options were just awful. I could barely tell there was a numerical difference between each state. I tried other colors but to no avail.
I took the data and imported it into openheatmap.com and bam! Worked like a charm. I was trying to plot some data on the 50 US States and was just having a miserable time doing it Excel. Excel isn’t free. Excel isn’t cheap. Sure, I could have tried libreoffice – which I did – but had some issues with all the data. 10,000+ rows is too much for a pivot table in a 32 bit application. Had to uninstall and install a 64 bit version.
For me, openheatmap was awesome. Putting your data into a visual representation has always been more helpful than displaying columns and rows of data. In this instance I was actually surprised at the results that it showed. The data will be used to direct marketing money to different states.
