I need to make a chart simulator. My plan is to have it display 50 bars with the ability to scroll back and forth for all the loaded bars.
when new data is added, i.e. more bars are loaded the chart will scroll forward, always showing only 50 bars.
i also want to have the ability to draw a simple dot on the chart and have my program keep the dot at the place i drew it at despite reloading with new bar information.
is this possible?
