问题 I've been playing around with Rally app customizations for about the past month now and have been impressed with the features that are available. I've been throwing the idea around to develop the legacy "Task Board" app over to the new Cardboard-style app. I've searched on GitHub and all of the documentation for similar endeavours but it always seems like individuals just try to update the legacy app. I would like to know if this is because of existing limitations with the Cardboard

问题 We are using Extjs 6 and we are using sencha cmd to build our application. We are facing one issue.

问题 Trying to use the colorfield UX and the default is that after you choose a color it shows the hex value of that color in the picker.

问题 I have a line chart with x Axis being numeric and y axis being numeric as well. I want the y axis to be reversed so that higher values are at the bottom of the axis and lower values at the top. I looked at the API Docu and didnt find a config to reverse the axis or so. Any clues? 回答1: In ExtJS 3 there was a reverse config option to get this going. With ExtJS 4 you have to use workarounds. For reverting the x axis values you could use the sorters property of the store connected to the chart.
