I have a simple series of temperatures at a weather station. Using the latest AgCharts as of 3/24/2025. Using Angular 19. When the value of the temperature is 0, no bar height is displayed, and therefore no tooltip is generated.

Ag Charts places the 0-axis in the vertical middle and draws bars from that down for negative values and from that up for positive values. When the value is 0, no bar is drawn and therefore no tool tip is generated on a mouse over.

Is there a way to fix that case?
