You can't interact with the graph by clicking data points (although you can drag curves around with the mouse), so you have to use the data editor. If you untick a record, it won't be considered in the fit (useful for fitting only to sections of the data).įityk is a useful app, but it can be frustrating to use. Just one more pointer - press Data | Editor. When you want to see the whole graph again, press the 'View whole' button on the toolbar (looks like a magnifying glass). Click and drag in this pane to zoom in on a section of the graph. Right-click on this area to change comparison modes. You can use this to show the deviation of each data point from the fitted equation, which makes it easier to identify possible anomalies. You'll see that just below the main plot is an auxiliary plot. This will run a fitting algorithm and find the best fit for your data. For the fun to begin, press the next button to the right, 'Start fitting'.

This will just plonk a new line on the graph.

Then, press the button right next to that drop-down, 'auto-add'. What does your data look like? There's a drop-down box on the toolbar which lets you choose what type of function the program should try to fit, so obviously choose 'linear' if it's a straight line and so on. This will make it easier to see what the hell you've got! Fityk will plot your data on the black graph pane - right cick anywhere in this area and choose a larger 'data point size'. Press Data | Load File, change the file type to 'all files' and open the file. Get your dataset in CSV (comma seperated value) form and fire-up Fityk. It still took a while to get any use out of it, though.

It definitely has a learning curve, but fortunately there's a comprehensive manual to help out. I've been using it to fit functions to lab data, and it works pretty well. So here goes.įityk is a curve-fitting application with a moderately intimidating interface.

I've decided to blog about some of the software I've been using to make my life easier, and maybe some of the music that I've been enjoying too.
