linegraph

问题 I have a line graph which tracks days passed on the X-axis. I would like for the data points to be visible on only the first entry and the last entry. I tried the below, which I thought should show only the final entry, but in fact had the opposite effect. =iif(Last(Fields!DateTime.Value),False, True) Changing from the Last to the First (or Max or Min) all have the same effect. An example with data point on only the first entry: Many thanks. 回答1: I figured it out. I needed to show it

问题 I have a column graph, that shows a trend of consumption over time, The y-axis being consumption and x-axis being time in month, I have to implement a target consumption.

I want to be able to pass my array to the object and generate a graph, but when calling my paint method it is asking me for a Graphics g... This is what I have so

问题 I am trying to generate a legend for a line graph I have created using ggplot. From what I have been reading, the legend should be made automatically given I have changed the aesthetics of the graph and included the linetype within the aes function but it is not visible. I have been scouring through answers to this exact question online and have tried many approaches but nothing seems to be working. I think I am missing something quite minor. I tried using scale_linetype_manual but this did
