Connecting Line: connect data points with lines to create a continuous
plotted line

graph based on the data. Autoscale is always the default scaling choice
for Data Pro. Autoscale will select the axis scales so that all the data just
fits on the graph while still following standard scientific graphing rules

perform a more limited autoscale by choosing Autoscale from Zero
•
By choosing Manual, you can choose both endpoints of the axis. Enter
the minimum and maximum values to plot in the text boxes.
