What widgets do you use to create a bar / bar graph?

Hi

still now, i using time series widget to display dynamic log value(i.g. sensor data)
but some demos display log using line/bar graph in mashup
how i get line/bar graph(chart)?
i downloaded Custome chart widget from Thingworx marketstore and display log using that
but that was not show line/bar together
and Custom chart widget just display value only one

How i show log value at chart via line/bar?

I want combine a line chart and a bar chart
