Line Chart display choices

ChartMaker can display Line Chart x-axis category labels as 'numeric' or 'non-numeric' using XisNumeric. If XisNumeric is false the grid alignment can be set using XgridAlign. This shows how you can use different combinations to display the output you need.

XisNumeric

`XisNumeric=false`	Category labels are shown exactly as you specify them. They are treated as text and can be words, numbers or any combination... To show a zero start, specify '0' as the first Category with a null (empty or -0) first Value... All the above apply 'XgridAlign=true' so the labels and chart points line up on the vertical grid. If we choose 'XgridAlign=false', the labels and chart points will align between the vertical grid lines like this... Whether the alignment is on or between the vertical grid lines is your choice. The default is 'false' i.e. between the gid lines.

`XisNumeric=true`	Category labels are shown as the numeric count of the category. XgridAlign is automatically implemented. Any Category text is ignored and may even be omitted... i.e. there no difference whatever the choice of Category labels or whether XgridAlign is true or false. Using `XisNumeric=true` is primarily of use when the data is to be presented with an automatic numeric sequence on the x-axis, such as in formula charts.

Can ChartMaker extrapolate categories?	No. ChartMaker only displays the data you supply. If you only have data for the 1st, 10th, 50th and 100th category the chart will display them equally spaced along the x-axis. XisNumeric=false, XgridAlign=true... XisNumeric=false, XgridAlign=false... To display all categories 1-100, fill in the missing values with nulls...
