3 diff charts using google charts visualizations api

I have some data different data sources which i would like charted. Here is some info and i have attached samples of what i would like it to look very similar. 1. Bar chart. this one is simple, i will pass 2 values (max and stat) ex. max=4 stat=6.8 ![][1] max=4 stat=3.8 ![][2] 2. Line/area chart. this one is more complex, i will pass an array of logs containing only 3 values (start time (unixtimestamp), end time (unixtimestamp), and traffic in KB). this is for a 24 hour period ex. it should draw a chart like the one below, paying attention to the times where its idle, notice there is no area under the line. also some of the logs overlap, meaning at any given time there could be 2 or more transaction logs happening concurrently which means the graph would be higher (notice the spikes in this one may be from multiple logs at the time, not necessarily 1 log of high traffic) ![][3] 3. other chart. not sure what this is called, but the data that i will pass you will be similar to above, except the chart should look like this (this is for 24 hour period): ![][4] notice the grey lines in the chart above is for no activity. and green means there was activity. ## Deliverables deliverable will be 3 php functions in 3 seperate php files which accomplish each chart.
