In the last post, we talked about scaling the Y-Axis of ZOOMS trends. What about the X-Axis?

Well, the X-axis (or as pedantic mathematicians would call it, "abscissa") for ZOOMS is always the time-axis. As with any chart, there is an "x-min" for the minimum value of x as well as an "x-max."

In the world of time-series data, there are more colloquial names:

In the world of time-series data, there are more colloquial names:

- x-min is starttime
- x-max is endtime

Unfortunately, there are also hundreds of ways of representing time:

ZOOMS is able to interpret a lot of date inputs, but not all of them.

There are 3 buttons at the bottom of each trend.

When you release the mouse button, the trend will zoom to the selected time range.

### Type Time Range into Search Box

And typing in the starttime and endtime is one way to set the time range:ZOOMS is able to interpret a lot of date inputs, but not all of them.

### Use the Trend Buttons

What happens when you've got a trend and you want to go from there?There are 3 buttons at the bottom of each trend.

**Back Arrow**is an arrow pointing to the left that will take the trend one time-range into the past.**Forward Arrow**is an arrow pointing to the right that will take the trend one time-range into the future.**Refresh/Revert**will restore the time-range to the original as-loaded trend.

### Highlight Area On Trend

You can magnify a time range by highlighting it with the mouse: clicking and holding down the mouse button at one edge of the time range and dragging the mouse to the other edge of the time range:When you release the mouse button, the trend will zoom to the selected time range.

### Summary

In summary, there are at least 3 ways to scale the X-Axis of a ZOOMS trend:- Type in the time range in the search box.
- Use the "back" and "forward" buttons
- Highlight an area on a trend
