The X-axis label should be something like the following: <HyperlinkButton Content="*Name Property Here*"

问题 I am studying ggplot in R and am trying to create a stock chart. I have already been able to create a candlestick chart, now I want to make a bar chart. This consists of a vertical line from the low price to the high price. Then, on the left of the line is tick for the opening price and on the right is a tick for the closing price.
