[Read New File] Scale X-axis Numbers [-] -
Sometimes it is desired to change the units with which the axis numbers were labeled. For example, from minutes to nano-seconds, for volts to kilo-volts. You can change the axis-label with the axis-label buttons. To change the X-axis numbers, click the the Scale X-axis Numbers button. A pop-up window appears allowing you to enter a scale factor. This will not change the data on the graph, nor its positioning. For example, suppose an experiment produced data ranging from 0.00002-seconds to 0.00005-seconds. Certainly such a span is unwieldy to express in seconds. Instead, you could change the axis label from being (units are seconds) to read (units are micro-seconds), and re-scale the x-axis numbers by 1.0e+6, to show values ranging 20-uS to 50-uS. The data and its position on the graph will be unaffected.
