For example, you can display chart values that range from 1,000,000 to 50,000,000 as 1 to 50 on the axis and show a label that indicates the units are expressed in millions. Tip Changing the display unit is useful when the chart values are large numbers that you want to appear shorter and more readable on the axis. To show a label that describes the units, select the Show display units label on chart check box. To change the display units on the value axis, in the Display units list, select the units you want. Note A logarithmic scale cannot be used for negative values or zero. To change the value axis to logarithmic, select the Logarithmic scale check box. Likewise, when you change the order of the categories from left to right, the value labels flip from the left side to the right side of the chart. Note When you change the order of the values on the vertical (value) axis from bottom to top, the category labels on the horizontal (category) axis flip from the bottom to the top of the chart. To reverse the order of the values, select the Values in reverse order check box. You can click Reset to bring it back to its original value if needed. To change the interval of tick marks and chart gridlines, for the Major unit or Minor unit option, type a different number in the Major unit box or Minor unit box. If not give a clear idea of the data set you are working with.To change the number at which the vertical (value) axis starts or ends, for the Minimum or Maximum option, type a different number in the Minimum box or the Maximum box. You want to plot every 5ms, right?, so that means 200 points per Second, not sure if I what I'm suggesting is practical. Keep in mind you don't need to complete every cell in col-A, just one value for every significant change.Īfter all that I'm not sure I thought through your original question.
Right click the X-Axis, Format Axis, Axis Options, check "Multi-level Category Values" (though it will probably have been selected by default). In the right panel (Horizontal Category), Edit, select the two time columns, eg col-A & col-B Select the data values in the 3rd column and create a Line chart Split the time values into two columns as I described before So for your purposes change the chart to a Line type as I suggested before, though that will only be appropriate if the time intervals are equally spaced and in logical order. However as "category" values points are plotted in order one after another. The difference might seem mute in certain scenarios but XY points can be plotted anywhereĪlong the X-axis according to the X-value. In most other chart types the X values are "category" values. An XY chart is a Scatter chart in which both XY values are regarded as "data" values.
