Plot official statistics' time series conveniently: automatic legends, highlight windows, stacked bar chars with positive and negative contributions, sum-as-line option, two y-axes with automatic horizontal grids that fit both axes and other popular chart types. 'tstools' comes with a plethora of defaults to let you plot without setting an abundance of parameters first, but gives you the flexibility to tweak the defaults. In addition to charts, 'tstools' provides a super fast, 'data.table' backed time series I/O that allows the user to export / import long format, wide format and transposed wide format data to various file types.

## Installation

You can install the development version of tstools from [GitHub](https://github.com/) with:

``` r
# install.packages("remotes")
remotes::install_github("kof-ch/tstools")
```

## Example Use:  Time Series Charts with Legends by Default 

{tstools} lets you draw time series line charts that come with a legend out-of-the-box. Simply
feed the `tsplot()` function with a list of time series. 


```{r example, message=FALSE}
library(tstools)
## basic example code
tsl <- list(
  AirPassengers = AirPassengers,
  JohnsonJohnson = JohnsonJohnson
)

tsplot(tsl)
```

and use easily use 2 y-axis. (I know some argue those double axes are fundamentally flawed, but my peers didn't care and asked for it.)

```{r}
tsplot(
  "Air Passengers" = tsl$AirPassengers,
  tsr = list("Johnson & Johnson" = tsl$JohnsonJohnson)
)
```
