title: How to filter out the null values in X-axis for Bar chart in Spotfire
body: <p>I am working with a data set where I have few columns with few null values in those. When I try to plot bar chart with these columns on x-aixs it is showing separate bar with this having no name.<br>
  Is there any way we don't show the null values in the columns as Bars.</p>

  <p>Please look into the image attached, I don't need to show the first bar with no name on X-Axis.</p>
