From 655cb952de5fc2b91ff7d6352131c2c0cde6e862 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 22 Feb 2019 09:27:20 +0200 Subject: [PATCH] perf scripts python: exported-sql-viewer.py: Hide Call Graph option if no calls table The Call Graph depends on the calls table which is optional when exporting data, so hide the Call Graph option if there is no calls table.
