I put a set of arrays into an x vs y plot with matrix input enabled. One set is frequency (X axis) in GHz (range .01 to 18), and the other is VSWR (range 1.0 to ~1.2). The x and y axis arrays are the same size & shape (3 X 52). This set causes the x vs y plot to show extra traces, some looking like a scope retrace. The other data set is similar, power on the X axis (range -36 to +20) and % error on the Y axis (range ~ +/- 3%) with just the numbers, no "%". This data sets displays normally with no extra traces. Does anyone have any clue what causes the extra traces to display and how to fix it?

Hi Drew

Most likely the answer lies in your data, not the plot. Would suggest posting the data from your two example plots.
