# Rotating and Scaling Plots

## Scanning Tilted Plots

Since version 3.2.0 xyscan does not allow scanning tilted plots any more but assumes perfectly aligned plots (i.e., not tilted w.r.t. the vertical or horizontal). Scanning tilted plots required precisely aligned markers (in x and y each) making the scanning of perfectly aligned plots (99% of all cases) more cumbersome. Instead xyscan allows now to rotate a plot once it is loaded before starting the scan. To do use the spin box (circled red below) in the Plot Adjustments dialog (`View->Plot Adjustments`). Units displayed are in degrees. Use the crosshair to check for horizontal and/or vertical alignment. The plot rotates around its center. Rotating a plot is disabled once a marker is set.

Note that xyscan cannot handle distorted plots of any kind other than tilts. It is strongly recommended to correct distortions beforehand using one of the many graphics manipulation programs on the market.

For convinience you can also scale (zoom in/out) the plot using the right spin box (circled blue above). Note, that zooming in will typically not increase the precision of the scan.
