Hi Mark,
The option "Zooming or Scrolling X Axis Limited to Data Range" may not be working quite right. Indeed, when we scroll one day / week / month / year later, when the last price is reached it should stop scrolling, and the display date range should be the last day / week / month / year to date. But what is displayed instead is the next day / week / month / year after the last price, so an empty graph without any prices.
Same in the other direction, when we scroll X axis one one day / week / month / year earlier and when the first price is reached.
