The points in the second chart are not equally spaced, since the slots for each day are equally spaced given rounding errors across pixels and the months have different numbers of slots days. They are identical: Note that the next red gridline comes before the next blue gridline: As before, copy the weekly data, and use Paste Special to add it as a new series to the char. To allow display of all points in the weekly series, format it so it appears on the secondary axis.
Excel at first only draws the secondary vertical axis below left. Rescale the secondary horizontal axis so it matches the primary: Finally, you can do a little clean-up. Delete the secondary vertical axis, and all data will be plotted on the primary scale which was the same anyway. Hide the secondary horizontal axis by formatting it to use no line and no labels below right.
No matter, will fix it in post. Copy the weekly data, and use the by now ultrafamiliar Paste Special to add it to the chart below left. The reasonable major unit of 30 days gives me funny dates: Well, we can hide the axis labels and add a dummy series with data labels that provide the dates we want to see.
How to Graph and Label Time Series Data in Excel
Here is the data for our dummy series, with X values for the first of each month and Y values of zero so it rests on the bottom of the chart. Use Copy — Paste Special to add the new axis data to the chart as a new series below right. Add data labels below this new series below left , and format the labels to show X Value, not Y Value below right.
Finally do some clean-up. Delete the Axis legend entry click once to select the legend, again to select the Axis entry, then click Delete. Make the plot area a bit narrower so the date labels are centered under the markers. I deleted the vertical gridlines, because they did not line up with the axis markers below right. A more important case for using an XY Scatter chart for a timeline is when the spacing of points is on the order of hours or less, rather than days.
The data below shows four unevenly-spaced points per day over a two day span. This was the same problem our first line chart attempt ran into while trying to plot multiple days within a month, when the base unit was Months. In Excel and earlier, you could plot an XY series along a Line chart axis, and it worked really well. The line chart axis gave you the nice axis, and the XY data provided multiple time series without any gyrations. So the process was, make a line chart from the monthly data below left. Copy the weekly data and use Paste Special to add it to the chart.
Only four points were visible, but be patient below right. Change the weekly series to XY Scatter type below left. Finally, assign the weekly XY series to the primary axis below right. In fact, this is one reason I was so slow to adopt Excel Try the same process in Excel or later this is Excel Convert the weekly data to an XY type below left , then move it to the primary axis below right.
Everything was cool until the real maintenance saving step of using the primary axis for everything. But on the primary axis you can only plot as many XY points as there are points in the original line chart series. In fact, there is a pretty reasonable and not too convoluted way to get multiple timelines with different date sequences on the same chart. It requires laying out your data differently, and tweaking the chart in the most minor but slightly obscure way. Start with your monthly data in A1: Add the weekly dates below the monthly dates A6: Add the weekly values below the monthly values, and one column to the right C6: C18 , with the weekly header in C1.
You can repeat this using more rows and columns for many more series as well. Looks pretty good, except for the gaps.

Why are there gaps, anyway? Excel puts a gap between points that have blank cells, but my data had no such gaps. Well, in a line chart with a date axis, Excel sorts the data behind the scenes before plotting it. This is easy to fix. Scatter Charts can begin with the X-Values in any column. It seems to me that most time series would need to be Scatter charts, as evenly spaced X-data would be a special case.

Excel plot time series frequency with continuous xaxis - Stack Overflow
No worries. Thank you for taking time to look into it. I started using numbers because presenting those fancy google charts on iOS platforms is next to impossible. So it seems Numbers has all the bells and whistles but with a different style or use. Aug 21, Communities Contact Support. Sign in. Browse Search. Ask a question.
