It is recommended that you look through these questions prior to calling Technical Support to see if your particular question has already been answered I have a very large data file but only want to look at a small piece of it and do not want to wait for the entire graph to be displayed How can I do this There are two common ways to only display a small portion of a data file The first method is to access the Edit Scales dialog and enter values for Time Start and Time Stop if you know the starting and stopping points you wish to plot ID 2000 will only plot data starting at the data point corresponding to Time Start and stop plotting at the data point corresponding to Time Stop A second method is to use the Quick Graph feature which draws a quick representation of the graph by only plotting selected data points Turn the quick graph feature on in the Plotting Preferences dialog then go ahead and plot the entire graph When the graph has finished plotting then turn off the Quick Graph feature and zoom in on the section of data desired I am manually scaling my graphs but the scales are not the same as what I entered in the Edit Scales dialog What is wrong There are conditions when ID 2000 will not use the exact scaling numbers that you specify for manual scaling This is because ID 2000 will not use non standard scales These types of scales have grid intervals of an abnormal number such as 3 6 7 9 etc or sc
