Show 1 Row of Data in a Chart

i am having a problem showing just one entry of data on a chart.

at the beginning of the month my charts empty out and start showing data from the current month for various data. but on the first day of the month no graph will appear. the chart requires 2 data points to start displaying a trace.

is there a setting on the chart to start the trace at 0,0 and continue from there, or will i have to script something?

attached is an image of one of my charts. it has one data point in the data set which is a value of 1 on december 11

Choose a pen renderer that includes a symbol at each point, instead of just a line.

I have the Render set to XY Line/Shape Render. and the type is Lines and Shapes. until i have 2 entries in my data set it will not display anything
