You can search for charts across all chart files.
>> To find a chart that has been saved in a file
You need to start in the "Selected Charts" pane. (You can get to that pane by tapping on the Charts tab at the bottom of the screen)
1.Tap on the > at the right of the details panel of any of the selected charts. This will present a list of options for selecting that chart.
2.Tap on the Select from File option. This will either present the "Files" pane showing a list of the chart files on your device, or will open the actual chart file that the selected chart comes from, listing all the charts that it contains (if it's this latter result, you can now skip to step 4).
3.If the "Files" pane is showing on the screen, then tap on the Search 
icon. This will open up a pane where you can specify either the whole chart name to find, or you can enter just part of the name (i.e. a "string") and all charts with that string within their name will be searched for. The search starts as soon as you start typing, and continues to adjust as you type in more characters.
4.Once the chart you want is showing in the list, tap on it to select it.

4.If there is only one chart file then when you tap on the "Select from File" option that file will be immediately opened. And sometimes even if there is more than one chart file that also happens. If there is just one chart file you can look in the file itself for the chart you want. If there are more than one chart file, then to go to the "Files" pane tap on the return arrow 
in the Tool Bar in the top left of the screen.
