My QCharts are locking up.

Chart Scrolling - Looking back into history...

Method #1 (slow) - select a chart - say a one of the "minutes" charts (as opposed to a daily or weekly chart) - and scroll back. You can use the mouse to drag the chart back, or you can use the left arrow on your keyboard to scroll back. Both will work and both are slow. If you're in March of 2006 and need to get back to March of 2000, and you're on a minutes chart, it's gonna be a while.

So....use:

Method #2 (fast) - Hold down the "Control" key on your keyboard while you are using the left arrow key on your keyboard. This puts you into "hyperspeed" scroll mode and will get you backwards into the history of a chart quickly. You can even hold the Control key and left mouse arrow down and it'll scroll so fast it'll out run the data - but don't worry - when you let up on the keys, the data will catch up. When you are scrolling back, if the candles disappear, you can press "Enter" and it will bring them up into view at the time that you are scrolled back to. Then, when you are done looking back in history and want to return to the present time, just press the "Home" key to automatically bring the chart back to today's price action.

Method #3: If you have a wheel mouse, you can click in the chart that you want to scroll back on and roll the wheel and it will scroll the chart backward.

Also note, that when you are backwards into the chart looking at the history, the colorful price and studies indicators on the righthand side of the chart will go to gray - not color. This lets you know that they are looking at historical, not current data.

More Scrolling Tips:

• The left and right arrow keys on the keyboard to scroll the selected chart back and forth in time by one bar with each press. Turning the mouse wheel scrolls the selected chart also (assuming Windows has the wheel enabled for scrolling).

• Holding down the Ctrl key and pressing an arrow key scrolls a screenful of bars with each press of the arrow key. Holding Ctrl down and turning the mouse wheel accomplishes the same thing.

• Holding the Shift key moves all charts the same number of bars with each press of an arrow key (same for the mouse wheel.)

• Pressing Home resets the selected chart back to the present bar.

• Shift Home moves all charts back to the present bar.

• You can combine Ctrl and Shift also. Control-shift-arrow keys moves all charts one screenful of bars.

• The shift key can also be used when clicking the Chart Toolbar buttons. For example you can change all charts to a line chart by pressing shift while clicking the Line Display button.
